IGNITING DEVICE FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 623,871, dated April 25, 1899.

Application filed May 5,1897. $erial No. 635,176. (No model.)

To all whom it may concern:

Be it known that I, ADRIAN LIVINGSTON Bo- GART, a citizen of the United States, residing at New York, (Jamaica,) in the county of Queens and State of New York, have invented a certain new and useful Improvement in Igniting Devices for Gas-Burners, of which the following is a specification.

My invention relates to an improved means for utilizing the common torch in' gas-lighting, and is more particularly useful in the ignition of what are known as cluster-lights (gas-jets grouped closely together around a central standard) where the same have chimneys of the incandescent or Argand type, or to gas-burners surrounded by closed globes, as in pendent lanterns.

In the ignition of Argand or Welsbach incandescent gas-burners, as the lighted end of the torch must be held over the tops of the chimneys the latter are liable to be broken, smoked, or displaced from their proper positions, and, further, it is a matter of extreme difficulty to light all of the jets of a cluster without a change of position of the operator. Where a closed globe surrounds the cluster, much greater, if not entirely insurmountable, difficulty is presented.

The object of my invention therefore is to avoid and entirely overcome the objections above stated and to produce by simple and inexpensive means a device by the use of which the ordinary gas-igniting torch may be employed to light gas-burners of the kind described with ease and certainty without altering to any considerable extent the construction of such fixtures as have closed globes and without risk of breaking, displacing, or smoking the chimneys and Without requiring the operator to change his position.

My invention consists principally in the construction of a flash-pilot or ladder in such manner that the same shall project a jet of gas away from or below the cluster, fixture, or globe, which is first ignited by the torch, such jet then serving to ignite the flash-pilot, which later performs the work of lightingthe burners of the cluster. By this method instead of the torch being put into position by the operator to reach the gas to be ignited it is held away from the fixture at such a distance that it can neither smokenor damage the latter or its parts, and the is automatically projected to the ignited end of the torch.

In the accompanying drawings, Figure 1 represents an embodiment of my invention as applied to a cluster of incandescent gas lights in a pendent lantern with closed glass globe, the main controlling stop-cock being independent of the igniting-valve. Fig. 2 is an open cluster, the main and igniting valves being operated simultaneously. Fig. 3 is a sectional view of the spring igniting-valve used in Figs. 1 and 2, but shown on a larger scale. Fig. 4 represents an open cluster with a springcock instead of valve controlling the igniting device, the flash-pilot entering the base of the burners instead of terminating over the tops of the chimneys; and Fig. 5 is a side elevation of Fig. 4 With the burners removed to show the relative positions of the igniting parts more clearly.

Referring to Fig. 2, I have shown an ordinary two-light cluster provided with a main stem A, a controlling stop-cock B, and two branch arms provided with incandescent gasburners O. Screwed into the bottom or body of the clusterisavalve D. Proceedingtherefrom is a pipe E, pierced with holes and constituting a flash-pilot or ladder. Fig. 3 is an enlarged sectional view of this valve, in which e is the gas-inlet pipe, which is screwed directly into the bottom of the fixture.

f is a conical valve which slides within the casing g, butis pressed firmly upward against the valve-seat by means of a spiral spring h, thereby normally preventing the issuance of gas from the fixture to the valve-chamber. The lower prolongation of the valve f is a rod 71, which passes through' an opening, not necessarily gas-tight, in the bottom of the valve-chamber g. From one side of the valvechamber issues the flash-pilot tube E, which is provided with two openings in its Wall, one above at j and the other below at It. If a downward pull be exerted upon the stem 2', as by means of the chain F; the plug f will leave its seat, permitting the gas to pass in through the passage 6, and so out of and through the flash-pilot pipe E. The movevalve 13 should it be depressed by means of its chain II, and in the figures it is shown as so depressed or turned on. One of the chains II and the chain F (attached to the ignitingvalve D) are connected together in such a manner that if a pull be exerted upon both chains at the same time by means of the common ring I both main valve B and ignitingvalve D will be opened to their fullest extent.

J represents an ordinary alcohol or other torch. To the side of its stem is attached a projection or hook K, designed to engage in either one of the rings at will.

The operation of the device is as follows: If the parts be in their normal position, the igniting-valve D being closed firmly upon its seat byits spring, and the main supply-valve B also closed, its arm G being elevated instead of depressed, as shown in the figures, the alcohol torch J is first lighted and its projection K engaged with the ring I. If now the torch J is drawn downward, the ring I will also be pulled downward and the main valve B opened to its widest extent by the lever-arm G assuming the position shown in the figure, and at the same instant the igniting-valve D will be opened fully. The gas will then pass through the main valve downward first to the burners, filling them and expelling the air, and then through the igniting-valve D into the flash-pilot pipe E, issuing through the various apertures made therein. That issuing from the lower aperture 7; will be projected downward, as shown by the dotted lines, striking the flame at the top of the torch, which will ignite it, and this ignited jet will consequently ignite that proceeding from the upper openingj, which latter jet will ignite those above it, so that the flame will travel upward along the flash-pilot to the extreme end thereof, thereby lighting the burners upon the cluster from apoint above the chimneys. If the pull upon the ring I be now relaxed, the igniting-valve will be closed by means of its spiral spring 7L, thereby extinguishing all of the jets in the flash-pilot, but leaving the burners lighted. The burners of the group may be extinguished at any time by pulling the ring I downward.

Referring to Fig. 1, the igniting device is shown in connection with a cluster inelosed within a glass globe. In this case, as the main valve 13 is located above the cluster, the turning on of the main gas-jet is independent of the turning on of the igniting-valve. A small opening L is left at the base of the globe M, through which the chain F passes from the igniting-valve D, which is located within the globe, as shown, its ring being attached exteriorly. The operation here consists in first turning on the main valve B, as by pulling the proper dependent chain, after which the hook upon the ignited torch is introduced into the ring I and a downward pull exerted, which opens the igniting-valve, causing its downward jet to pass through the opening in the glass globe and become ignited at the lighted end of the torch. As before, when the pull is relaxed, the igniting-valve closes, extinguishing the flash-pilot.

In Figs. 4 and 5 the igniting-valve consists of an ordinary stop-cock N, about the plug of which is arranged a spring 0, which tends to keep the said cock N normally closed. The operation of ignition as far as the valve and pilot-tube are concerned is the same as that described, as shown in Figs. 1 and 2. In these figures is also shown a modification of the flash-pilot. Instead of the flash-pilot proceeding upward and terminating above the chimneys of the burners it branches at the point I, each of the branch arms separately passing within the Welsbach burner to the proper igniting-point. This latter form is in some cases preferable to that first described of lighting from the top, particularly where a gas of heavy specific gravity, like machine or gasolene gas, is employed, the latter having a tendency to fall instead of to rise.

I do not limit myself to the use of any specific kind of valve to control the ignitingsupply, as it is to be plainly understood that any of the usual forms of cocks or valves could be used. This is also true regarding the flame or spark making torch, as any instrument will serve to ignite the downward jet that is capable of bringing such jet to ignitin g temperature. Although preferable, it is not necessary that the valve be pulled open by the torch itself, as the torch could be held in one hand and the igniting-valve opened with the other or by any other means.

I claim- 1. In a gas-lighting apparatus, the combination with burners, of a flash-pilot, a main valve controlling the gas supplied to the burners, a supplemental valve controlling the gas supplied to the flash-pilot, a spring tending to normally close said supplemental valve, an operating-ring I, a flexible connection between said operating-ring and the supplemental valve, and a separate flexible connection between said operating-ring and the main valve, whereby the said valves will be opened simultaneously by the operation of said ring but the supplemental valve will be allowed to close without alfecting the posisition of the main valve, substantially as set forth.

2. In a gas-lighting apparatus, the combination with burners, of a flash-pilot having a downwardly-extending opening at its lower part by which the flame from the pilot will be projected downwardly away from the downwardly-extending opening that the ini tial jet maybe ignited by the torch in depressing said ring, whereby both valves will be opened simultaneously but the supplemental valve will be allowed to close without affecting the position of the main valve, substantially as set forth.

3. In a gas-igniting apparatus, the combination of burners with an inclosing globe, an aperture in said globe, gas-valves for the burners operating through said aperture, and a flash-pilot wholly within the globe having a hole pierced therein for projecting gas through said aperture, for the purpose substantially as set forth.

This specification signed and witnessed this 28th day of April, 1897.
